General Description

• Observation of HD128898 with the instrument AMBER (one calibrated point)
   with the immediate objective of determining its angular diameter with an accuracy
   of 7% or better.
  
  From 15 of July 2006 to 30 of September 2006 the target is not observable (insufficient
   time up). 
  
  Two finding charts are attached to the science OB (SCI_HD128898). The first is the
   required chart in the optical and the second is a finding chart in the K band, where
   a second source, of lower magnitude in K is seen to exist not far from the target
   source.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• There are no critical observing conditions appart from those necessary
   to make sure that MACA0 performs properly for our target.

Time-Critical Aspects

• Does not apply

Special Execution Requirements

• Despite the fact that the quality of H-data is not guaranteed, we do not
   want to give-up the data in the H band as these data can improve significantly our
   measurement.  
  
  However, since we can gain in using IRIS as well, we propose that the execution
   is carried out according to the following steps:
  
  (1) first point the target with IRIS (the gain in observing time/overhead is important)
   and acquire interferometric data in this mode in K band.
  
  (2) second, remove IRIS and record interferometric data in H and K bands in a"blind"
   mode.

Special Calibration Information

• Two possible calibrators were selected from CalVin. Our first choice calibrator
   is HD148890 
  (OB NAME: CAL_HD148890).
  
  However, beacause this star is 11.8 degrees away from our science target (HD128898),
   we have produced an alternative OB for a second choice calibrator HD133869 (OB NAME:
   CAL_HD133869), which is only 4.6 degrees away from the science target. This calibrator
   should be used only if it is not possible to use our first choice calibrator.
